3. Compared with the cascade without slot, the surface load of cascade with slot increases near the leading edge and trailing edge and decreases at the slot inlet. 通过开槽处理，改变了叶栅表面的静压分布，使叶栅前段、后段的负荷增大，小槽进口附近的负荷减小。
4. The results show that a longer expansion period and a better expansion could be achieved with the blast furnace slag as expansion agent. 结果表明，用钢渣做膨胀剂，膨胀龄期较长，膨胀状况良好。
5. Expansion monomers and expansion polymerizations, noted for their volume expansion during polymerization process, can be used to modify the properties of epoxy resin adhesive. 膨胀单体和膨胀聚合反应的特点是在聚合过程中能产生体积膨胀，可以用于环氧树脂粘合剂的改性研究。
